Cake444 Posted April 28, 2011 Report Share Posted April 28, 2011 Thought I would post my findings in continuation with some older posts I made regarding Magtech 12g Brass Hulls in combination with a particular smokeless powder. Some of you may find this interesting, some not so much but there we go. I have only been reloading a short while mainly using 70mm PT cases and published loads plus the help of a forum member that was kind enough to give me some guidance along the way. Magtech 12g Brass Hulls are generally designed to work with black powder so there isn’t any load data for any form of smokeless from what I found but I managed to get a reliable cartridge together using A1/32g load. The main issue was lack of back pressure due to there being no crimp on the brass case. Silicone sealant and an overshot card just didn’t hold it all together long enough for a clean burn but the formula below gave really good results. If any of you decide to try this below then do so at your own risk as this is not any form of load data! I simply did this for fun and it also required me to convert the hulls to take 209 primers which a cowboy re-enactor kindly did for me free of charge. Magtech 12g 2.5 inch Brass Hull CX2000 Primer 26 grains Vectan A1 Use x3 10gage 4mm Nitro Card 10gage 1/2 inch Fibre Wad 1mm 11gage Card 32 grams #6 Shot 1.5mm 11Gage Overshot card Sealed with a blob of Evo Stik Flexibond and tidy up with a cloth to remove excess. The flexibond has given me no residue within the barrel and when dry it’s rubbery but tough so it holds the case closed for long enough to allow for a build up of pressure (primers obviously help alongside the three over powder cards). The hulls can be cleaned very quickly by using a 12g sized copper brush and reused until trodden on. I have no pressure testing equipment or a chronograph so I went on how clean the burn was, recoil and pattern testing. I also hit 34 out of 50 clays down at the range with them so they work quite nicely. Quote Link to comment Share on other sites More sharing options...
Jaguar Warrior Posted April 28, 2011 Report Share Posted April 28, 2011 (edited) What a class piece of work, Cake! I can only imagine how good it must have felt when that first clay shattered. Its also good to see how us 'newbie scumbag worthless novice reloaders' can contribute in a worthwhile way. We might lack the knowledge, but partly make up for it in enthusiasm and persistence. I'm giving Cake a silver star for this and proposing that he be promoted to 'wannabe reloader' Now who will second this?

Guest cookoff013 Posted April 28, 2011 Report Share Posted April 28, 2011 were the brass resizes prior to re loading? and the lack of "back pressure" is almost correct. pressure is pressure. there is no different types of pressure. back pressure, sidewall pressure, frontal pressure, its all the same. its just pressure. all powder burn clean at high pressure especially at 9000psi and more. thats the golden pressure to achieve with all loads. burns clean, and will give acceptable speed at that pressure. stabilize the pressure and the speed stabilizes. the pressure is the key. not the speed.

I have two sets of brass. 30 hulls take 209's and the other 25 take berdan No 56 primers. The cases using CX2000 had a bit more punch (slightly higher velocity) but the berdan primed still gave really good results and are more than acceptable. I'm off out today so i will see how i get on.

stirky Posted May 2, 2011 Report Share Posted May 2, 2011 Putting a 10 bore wad down a 12 bore barrel, is that wise ? Quote Link to comment Share on other sites More sharing options...
Cake444 Posted May 2, 2011 Author Report Share Posted May 2, 2011 Putting a 10 bore wad down a 12 bore barrel, is that wise ? Ive not had an issue with it and ive done over 120 carts. 12g Fibre gives poor sealing anyway (as ive been told many times). Quote Link to comment Share on other sites More sharing options...
